NFDM-478 Behind the scenes of M-man filming: naked ball kicking & electric massage ~Staff members are the practice subjects~ – Eri Takigawa (Misa Arisawa)

Most actresses have never experienced ball kicking or electric massage before. Ball kicking does not only damage the man's balls, but also the legs of the woman doing the kicking. For this reason, they need to practice how to kick before filming, and the practice subjects are the ADs, camera assistants, and sometimes even the director and producer, who teach while writhing in pain.
